RALPH B. WAITE, 0F SPRINGVILLE, NEW YOEK, ASSIGNOR T0 THE ANTIDOLOB MFG.CO. INC., A CORPORATION OF DELAWARE MEDICAMENT CONTAINER Application ledNovember My invention relates to medicament containers and isparticularly concerned with containers for medicaments which areadministered hypodermically. The object of the invention is to providean improved `stoppered bottle from which doses of the medicament may bewithdrawn by a hypodermic syringe whose needle is made to pierce apliable plug.

Medicament containers of these general characteristics are old in theart, but, as before stated, I provide an improved construction thefeatures of Which will be pointed out as this description proceeds.

This application is in part a continuation of my application, Serial No.221,909 which I filed on September 26, 1927.

In the accompanying drawings Fig. `1 is an elevational view of themedicament container of myinvention;

Fig. 2 is a sectional view, taken on plane of line 2-2 of Fig. 1 andlooking in the direction indicated by the arrows, and being on asomewhat larger scale;

Fig. 3 is an under side view of the pliable plug to which reference willbe made;

Figs. l to 7 show modications.

The container itself is in the form of a bottle 4. having the neck 5,formed on the outside with threads 6 and on the inside with a shoulder7.

The plug 8 of soft pliable material, such as soft rubber or composition,is disposed in the upper end of the bottle neck, this plug beingcircular and of such diameter as to lit just snugly within the enlargedupper end of the bottle neck as shown. Furthermore, this plug is of athickness equal to the distance between the shoulder 7 and the top ofthe bottle. The result is that at no time is the plug under any morepressure than that which is absolutely necessary to keep it in its placewhen the bottle is inverted.

The underside of the plug 8 is hollowed out or cut away hemisphericallyas indicated at 9, in order to reduce the thickness of the centralportion at 10 for a purpose which will be referred to presently.

A metal cap 11 is threaded onto the bottle neck, as indicated, a corkdisc 12 being pro- 1s. 192s. serial No. 319,897.

vided in the cap to be forced down upon the top of the bottle. Inscrewing home the cap 11, no pressure is exerted upon plug 8, by reasonof the arrangement and relative dimensions which have been referred to.

When it is desired to charge a hypodermic syrlnge, the cap 11, with itsdisc 12, is unscrewed and removed, the needle of the hy podermic is madeto pierce the central portion of the plug 8, the container inverted, andthe syringe plunger actuated. The syringe needle is then withdrawn andthe aperture in the plug 8 is self closing due to the nature of thematerial of which it is made.

By providing an arrangement in which the plug 8 is neither compressednor relied upon normally to stopper the bottle, I am enabled to employ,for the plug 8, material best adapted for the purpose of closing thepiercings and best from the standpoint of cleanliness. Furthermore, thearrangement whereby the top of the plug is flush and edge to edge withthe top of the bottle neck contributes further to this essentialcleanliness.

In Figure 4, I show a modilied form to act as a treated gauze stripcontainer. In this case the plug Sais pierced to permit of withdrawal ofthe gauze therethrough with tweezers.

In Fig. 5 I have shown a further form to act as a container for atreated gauze strip.

In this case the plug 8b, similar to the plug 8a of Fig. 4, is reversedin position so that the recess 9 is on the upper side. In that position,as shown, when the end of the gauze strip is cut with a scissors flushwith the to there is, within the recess 9, a small protruding end whichmay be grasped by a tweezers. In this way the gauze is always ready tobe withdrawn, without diiiiculty.

In Fig. 6 I show a further modified form, in which an intermediate cap13, of cellulose material, pierced or cut away at the top at 14, isinterposed between the glass bottle neck 5 and the cap 11 of metal, thisintermediate cap l preferably extending down over Y the threads 6. Thisimproves the sealing of the bottle and also operates to hold the lug inplace against possible withdrawal iy the withdrawal of the needle.

Fig. 7 shows a modification in which the stopper 8 is extended down fromthe shoulder in the bottle neck, as indicated at 17, and is providedwith a flange 15 resting on the top rim of the bottle, a depression 16being provided in the top ofthe stopper to facilitate the piercing.

I claim In combination, a bottle, a closure means 10 therefor, saidclosure means having a recess in the outer surface thereof, and gauze orthe like passing through the closure means in line with the recess, saidrecess enablin the gauze to be withdrawn from the bott e through therecess so that after severance of the gauze a projecting p0rtion willremain in said recess for gripping.

In witness whereof, I hereunto subscribe my name this 25th day ofOctober, 1928.
